Solid Case or Soft Roll?

What sort of travel case do you prefer, something solid like the CWBC Donut or something soft like a traditional watch roll? Donut - Watch Roll -


I use Watch rolls instead of Watch boxes to store and display my watches at home. 


I also use a watch roll (3 watch). All leather and suede interior. 



When I'm going on holiday I put my watches in this it's hard plastic case,then goes in my hand luggage
